EBU club.

Have read the White Book section but I still find this confusing.

For example:

1NT - 2D* - P - 2S

2D by E is alerted and explained as Astro showing Spades and another suit. However E has forgotten the system and has 5 diamonds.

Let's presume that E is well-behaved and does not flinch or give any indication that the 2D is a misbid.

Would it be an infraction for E now to bid 3D having been "woken up" by partner's explanation? Holding, for example, only 2 spades? Of course there is a risk that W may now bid 3S or even 4S, but E may hope that W may be weak and pass?

Yes. You are 100% not entitled to any information from partner's alerts. You have to stay dumb, and bid as if partner thinks you have ♦, and he has ♠.

Your partner also may have a problem. When you bid 3♦ this looks like a game try so you're probably not playing there. If he passes, questions will probably be asked how many times it's happened before and there's a danger you'll be done for fielding a misbid in the EBU.

As a consequence you cannot simply pass 2♠ with a three card spade suit. You will have to raise "his" spades to the appropriate level. So you may well end up in 4♠ on a 3-3 fit. Life is hard when you misbid...
