One of the most important things in dominion is to have a plan. Preferably a good plan, but usually any plan is better then no plan.
After that, choose actions that are consistent with your plan.
Looking at this board, a couple of plans are worth considering. I think doing a clean execution of either one of these would have improved your play here:
- Silk Roads. Use workshop and/or smugglers to get lots of green cards and get them fast. Possibly Squire can help out a bit
- Embassy-BigMoney, supported by a Counterfeit. Buy Provinces.
- Build an Engine. Use Farming Village, Throne Room, Embassy to draw lots of cards.
Comments on these plans:
- Silk Roads looks like a decent option. Workshop isn't the best enabler, but not the worst either. Smugglers is also good here.
- Embassy-BM looks pretty decent too. Embassy is a very good card for BigMoney. Keep it simple though, cards that aren't yellow are bad for your deck.
- The engine looks pretty bad here. Embassy doesn't actually draw much, you can't get rid of estates and you have nothing to attack your opponent. (Attacks are good for engines because you can play them over and over again). Also copper trashing is slow and expensive.
I think I'd go for the Embassy-BM. Against a Silk Roads player, I'd deviate a bit and get some silk roads as well just to deny points. I don't see a 3rd pile (after Silk Roads & Estates) that goes fast enough to really scare me. I could be wrong on this one though.
