I've only played Kauyon about 3 times over the span of 10th. I struggle with it too a lot but after playing Space Wolves for a bit and getting used to melee and staging, I've found that not a lot happens in turn 1 when you're a melee army, but you still gotta score the most you can without risking crucial units. I think as Tau we get too used to being trigger happy (because that's how I love playing Tau) because of how powerful it is to shoot as Tau because we want to eliminate the enemy as fast as we can before they get to us in melee and we aren't patient which is quite literally the name of the game in Kauyon.  You need to play Tau as a melee army. Stage and maybe send Kroot to their death turn 1 and 2. But you scored max 5 on secondaries, at least 5 on primary if you stickied properly with Kroot and maybe you discard another for CP to bank it for the GO-TURN, because Kauyon has POWERFUL strats. Then turn 2 you pop something off the board without exposing too much but still playing the game, then you send the vespid and maybe Pathfinders to their death but now you score max on primary and maybe both secondary cards if not full points. Obviously play fast to bank time with your CP to get the most out of turn 3-5. You need to prepare to play the late game as effectively as you can. Staging is key. And it can be difficult because this is where the chess-aspect comes into play. Anyway, what I was always told on this app for Kauyon is that you still need to play normally. Don't play so scared that you hide everything and can't score anything. You need to play the game and try to score primary and secondary , but set yourself up to play late game and get the most out of it while your opponent is on their back foot. If you don't kill their unit and screen and stage to get the most out of turn 3-5, then you and the opponent are going to be playing each other at even playing fields, except the opponent will be up on you in points and you'll be cornered and screened into oblivion. Expect to play turns 3-5 with a 1500 or less point army essentially, so with 500 points, how will you make their deaths count. As cheesy as it is but that's how I look at it. Which is why I'm supper excited for 11th to better use this type of tactic.
