This match is a perfect example that the team should not give up. Chasing 328 for win, Ireland were 111/5 in the 25th over, needing 215 off 25 overs, which is a very difficult task for a T25 having all 10 batsman.
I voted for 'All out attack'; but it should be calculated counter attack. You can see Irish calculations in taking the powerplay at the right time, blind hitting does not work.
