TL;DR: TvP is my worst matchup and I've been reviewing my replays in order to identify my mistakes / what I ought to do differently next time. However, I'm starting to question whether I'm going about things correctly as I don't seem to be faring any better in this particular matchup. I'd appreciate folks' input on this particular game with regards to what I could have done better in this game, so I can compare it against my self-analysis (below).
In an effort to improve at TvP (my worst match-up by far), I've begun (an attempt to) review and analyze my replays with an eye toward finding key mistakes that cost me the game. In many instances, macro was the culprit. However, in recent games, I'm starting to think that it's my approach to engagements (w/ his army) that is to blame.
For context, I am in silver league, with just over 200 or so games under my belt. I started playing SC2 midway through 2015 Season 1.
Take for example, this game I played earlier today. I've reviewed the replay and attempted to identify the reasons I lost the game but I would appreciate if folks could confirm, correct and/or supplement my analysis. (Your comments would help me help myself when reviewing future replays, if that makes any sense).
- The game starts off with my opponent attempting a cannon rush at my natural. I pull SCVs to take out the warping cannons but the cannons do warp (albeit with limited HP remaining) and I end up losing 4-5 SCVs in the process - given the SCV losses, I think I'm marginally ahead at best (due to the fact I began constructing a second CC in my main and I think I can expand much sooner than my opponent).
- The game then enters enters an economy-building phase. At around the 12 minute mark, I attack his natural with a marauder-heavy bio army (which I discovered in the replay had a 25-supply lead on his stalker-heavy army, which also had zealots). I start my 3rd base as I move out. The timing is later than the usual 10 minute push but I figured that we were both set back by the cannon rush. He was slightly ahead on upgrades - he had +1 attack & +1 shields, while I had +1 attack and stim but I decided to attack after seeing I had a larger army, a large part of which countered his (i.e., my marauders vs. his stalkers). However, after a few quick warp-ins to replenish to his lost stalkers along with Photon Overcharge, I decided at the time that I didn't think I could trade effectively with him so I elected to retreat.
- The game then entered the late-game phase - up until this point, I've been able to simply overwhelm my Protoss opponent with macro/sheer numbers, but as my opponents have been getting better (this opponent was gold in 2015 Season 1; the previous season's ranking is probably more accurate than his current ranking given the ladder reset at the beginning of this season), this has proved more difficult. Nevertheless, I think it's more useful to look at the first 15 minutes of play, given that is where Terran would ideally have ended the game.
I think I made two big mistakes:
- I think my first big mistake was not preventing him from expanding to his natural. He expands quite a while after I expand and, although photon overcharge would have prevented me from destroying his main, I think I could have contained him to one base.
- I think my second big mistake was retreating during my attack at the 12-min mark. After watching the replay, I think I probably could have taken out his natural (albeit at the cost of most that army).
- I elected to add more barracks and make marauders/marines in lieu of medivacs prior to my 12 minute push because I thought that higher numbers would give me a better chance.
- Related to the previous point - following this decision to go for a more mineral heavy army, I ought to have reallocated SCVs away from gas and toward minerals. Although my overall spending quotient (67), it is largely due to the fact that I ended up banking gas. My SQ for minerals and gas separately was 82 (which could be better but is also not terrible) and 48 (which is just terrible), respectively. (As reference, my opponent's SQ was 57, with a mineral SQ of 54 and a gas SQ of 61, but I don't know if this metric is as relevant for Protoss given the warp-in dynamic.)
- Lastly, I think I ought to have taken a 4th much sooner - possibly immediately after my 3rd base, given I was able to saturate my 3rd base instantly.
- At this point (around the 15 minute mark), I stopped my analysis given that it seems pointless to analyze late-game mistakes which wouldn't have occurred if it hadn't been for my early and mid-game mistakes.
I would appreciate any thoughts/comments/criticisms. This particular matchup (TvP) is proving to be the most difficult one for me (by far).
