The two competing ways here are, as most of us agree, IW/Gardens rush and something based on WM and monuments. For the latter, you definitely want to open IW/chapel, several comments mentioned another IW, either at all or ASAP. In the first game, I went for IW/Gardens while Psyduck had 5/2 and opened militia/chapel (which is also pretty reasonable if you expect your opponent to go chapel, too). He then made the mistake to go for alchemists which was just too slow to do anything against the rush:

I managed to do that all three times, one of which was very close, though (funnily, it was the one with the highest VP difference, I believe, cause he was 2 cards short of ending it giving me the time to get ahead and another turn to increase the lead and end it). I indeed got a 2nd IW.
In the first game, I left caravans mainly aside, but I found them rather important so I went after them a little more in the following two.
Another thing is denying gardens or not. SCSN says he wouldn't do that at all. I did, when I figured from the second, pretty fast, game that one gardens more for him and one less for me would've led to a loss for me. I didn't try ignoring gardens, though, and ended up with 3 of them in every game. Also note that I bought expand in the first two (which is a clear mistake), and that he also picked up some WM which a) speeds up 3piling, b) enables him to play 2 IW for Gardens in one turn if he happens to hold WM/2 IW or draws a 2nd IW. We didn't have enough time to check what happens if he goes for Gardens earlier, disabling me from stealing 3. So this, and me ignoring Gardens would be interesting to check now. Or somebody try and simulate it, I've never really really dived into simulations.
